used, it has'been found Be it known that I, NATHANSULZBERGER,.

born in New York city, and a citizen of the United States; .residing at New York'city, in the county and State of New York, have invented new and useful Improvements in Catalyzers Containing Silicon and Processes for Making Same, of which the following is In all cases Where catalyzers have been v thattheir efiiciency isincreased, when such catalyzers are most finely distributed in the medium, which is ous solution of a distributed among the silicon-contai to be treated. One of the methods for accomplishing such fine distribution is toimpregnate an inert substance with the substance which is to be used as a catalyzer. As such inert substances have been pro posed among others, kieselguhr, kaolin, asbestosand the like.' The mode generally employed was to endeavor to saturate such substances with a solution, generally aquecatalytically efficient substance over an inert material containing. silicon, silica or other compounds containing silicon, is by utiliz: ing a chemical compoundcoritainingsilicon and such substance, which is to be usedas a'catalyzer. By this method,-since the original molecule contained both substances, the resultant product, which is to be catalytically employed, will'be most intimalgely 11g substance. -Thus the product described the following example, even when brought to an impalpable powder of velvety feel, ap-

subjected to a current of hydrogen, while.

aqueous solution of a nickel-salt was treated with a solution of sodium-sihcate. The precipitate was filtered olf, dried and tained. This which requires time, labor and machinery;

o substance was used as acatalyzer, forinstance, in hydrogenating oils, with which it can readily be mixed, remaining well in suspension, which fact may be duethat the product likely contains silicic acid also in a colloidal condition.

.Various modifications of the above described illustration of my invention may be employed. Thus, tion of the metal-silicate may be accomplished-in solution by means, for instance, of hydrazin or some other reducing agent. Mixtures .of substances, as, for instance, of silicates: nickel silicate with small amounts of palladium, may be employed. All such and other modifications come under the scope of this invention, the fundamental idea of whichis the utilization of a chemical combination per se or in mixture containing silicon and a metal, Whichis catalytically efficient: Y

The claims cover not only larly specified ingredient (silicate,

being heated. A black powder as silicates,

silica impregnated with metal, etc.), but. also all mixtures of same with substances, as

will not destroy catalyst. By the term free from anti-catalytic material in claims: 1, 2 and 3, is meant, free from anticatalytic material and such amounts of same, as will destroy the catalytic actioi'z' of the product. The word hydrogen in the following claims also includes mixtures containing this element, as

' well as all such other processes, which are effective reducing agents in consequence of their hydrogen contents. I claim:

1. A process of making a catalyst, which comprises reducing a silicate of a' catalytic metal with a reducing agent free from ant1- catalytic material.

2. A process of making a catalyst, which comprises reducing a silicate of catalytic metals with a reducing agent free from anticatalytic material.

3. A process of mak ing'a' catalyst, which comprises reducingfnickel silicate with a reducing agent free from anticatalytic material.

4. Process of making a catalyst, consisting in reducing metal by means of hy rogen.
